If Tom is too cautious to be a good Godfather, Sonny would fail for the opposite reason. He lacks the restraint and sangfroid (self-possession) that make his father and brother so successful. All heart, no brains, he is rash, impulsive, and sometimes just plain stupid. Too often, he acts before thinking. This recklessness gets him killed, as he walks right into a death trap by hurrying out of the house without bodyguards. A man of strong appetites and passions, he cheats on his wife and is barely able to restrain himself from beating his brother-in-law to death when he learns that his sister has been abused. We see a lot of Sonny in Vincent, and we cannot help but wonder how Vincent will lead the Corleones as Godfather—whether he will learn from his uncle or repeat his father’s mistakes.
